Have used these many times ... My partner has gotten me a little nervous when using the poly fittings for heat loops so went back to these for that purpose!

Great Reducing Fitting
Used these at the end of a run to transition from the 3/4 in. to 1/2 in. to supply a shower. Worked great. Priced excellent. I called to have these added to my order after I realized I had forgot them. No problem. They took real good care of me. They arrived quickly. I was really impressed and surprised. Thank you Pex Universe Dot Com.

best price
these fittings are pretty much the same everywhere, same as sharkbite etc. So really its just where the best price is, which when i bought them was here. I was working with a plumber friend on my house and even with his contractor discount at the local plumbing supply house, everything i bought from there was the same price or less on this site, i would have ordered everything here if i knew before starting the job. We put a new boiler, water heater and all new pex in the house because it was abandoned and copper was stolen. So when i saw everything was cheaper on this site i mean, the fittings, rolls of pex, valves, all the parts for setting up a boiler including the taco boxes and taco circulators.

Ask a Question
What is the difference between the regular fitting and the lead free fitting? Are they both brass?
Helpful? Yes No
Yes, they are both brass. The difference is in the composition of the alloy:
Lead-free fittings are made from C46500 alloy brass, which has less than 0.25% lead by weight as required by the Safe Drinking Water Act (which came into effect nationwide on January 1, 2014). These fittings are therefore suitable for potable water applications.
Regular brass fittings are made from C35200 alloy, which has more than 0.25% lead by weight and is therefore not approved for potable water use, but can still be used for PEX heating applications and for non-potable water applications.
Both alloys are DZR (DeZincification Resistant) brass.
